DETAILED DESCRIPTION OF THE EMBODIMENTS

The inventor of the present invention conducted intensive studies. As aresult, the inventor found that, as a result of providing one or morefirst fasteners in a wig base cap, providing, in a hair member, a secondfastener having adhesiveness to the first fasteners, separably adheringthe second fastener to the first fasteners, and fixing the hair memberto the wig base cap, a wig from which the hair member is unlikely todetach can be easily produced in a short period of time.

In one or more embodiments of the present invention, the wig kitincludes a wig base cap and one or more hair members. The wig base capneed only have a cap shape to be worn on a head, and is not particularlylimited. In one or more embodiments of the present invention, anartificial skin base (also referred to as a “skin base”) may be used asa wig base cap, for example. Although there is no particular limitationon the artificial skin base, a polyurethane resin film or sheet that isgently curved in a protruding shape following the head shape of a usercan be suitably used, for example.

In one or more embodiments of the present invention, although notparticularly limited, from the viewpoint of increasing air permeabilityand comfort when the wig base cap is worn, it may be preferable to use anet base at least partially constituted by a net cloth, and it may bemore preferable to use a net base entirely constituted by a net cloth.In one or more embodiments of the present invention, although notparticularly limited, a cloth woven in a mesh pattern, a cloth providedwith through holes, or the like can be used as the net cloth, forexample. Although there is no particular limitation on the material ofthe net cloth, examples thereof include chemical fibers and naturalfibers. In one or more embodiments of the present invention, from theviewpoint of being able to easily fit to the shape of the head of auser, the net base may preferably have elasticity. A commerciallyavailable cap for a wig or the like may be used as the net base, forexample.

In one or more embodiments of the present invention, although notparticularly limited, a region of the wig base cap that covers theforehead may be provided with an opening portion. Hair of a user can bedrawn out from the opening portion. Alternatively, as a result of fixinga hair member having a part to the opening portion, a more natural wigcan be obtained as later described.

In one or more embodiments of the present invention, there is noparticular limitation on fibers used in a hair member, and fibers forartificial hair, such as natural fibers and chemical fibers, can beused. Examples of the natural fibers include human hair and yak hair,and examples of the chemical fibers include synthetic fibers such aspolyester-based fibers, acrylic fibers, vinyl chloride fibers, andpolyamide fibers, and artificial protein fibers such as collagen fibers.

In one or more embodiments of the present invention, the hair membersmay include a hair tress constituted by a fiber bundle having a rootportion where fibers are linked to each other. The hair tress (alsoreferred to as a “weft”) is normally obtained by sewing one end portionof a fiber bundle having a predetermined length using a sewing machinefor wigs, and processing the sewn fiber bundle into a grass skirt shape.A sewing portion of the hair tress serves as the root portion. In one ormore embodiments of the present invention, the second fastener isnormally provided at one end portion of the hair member, and forexample, if the hair member is a hair tress, the second fastener isnormally provided at the root portion of the hair tress.

In one or more embodiments of the present invention, the hair membersmay include a hairpiece constituted by a base portion and fibersimplanted in a central portion of the base portion. In one or moreembodiments of the present invention, although not particularly limited,normally, the second fastener is provided at a peripheral edge portionof a base portion of the hairpiece. In one or more embodiments of thepresent invention, the hairpiece may have a part. In one or moreembodiments of the present invention, a hairpiece having a part may bepreferably fixed to the region of the wig base cap that covers theforehead, and may be fixed to an opening portion disposed in the regionof the wig base cap that covers the forehead. In one or more embodimentsof the present invention, although not particularly limited, similarlyto the wig base cap, an artificial skin base may be used, or a net basemay also be used as the base portion of the hairpiece, for example.

In one or more embodiments of the present invention, the wig base cap isprovided with one or more first fasteners, and the hair member isprovided with a second fastener having adhesiveness to the firstfasteners. Because the second fastener has adhesiveness to the firstfastener, the second fastener can be easily separably adhered to thefirst fastener. In one or more embodiments of the present invention, “asecond fastener having adhesiveness to a first fastener” means that thefirst fastener and the second fastener separably adhere to each otherdue to an external process involving the use of pressure and/or heat,for example. In one or more embodiments of the present invention, “asecond fastener and a first fastener separably adhering to each other”means that the adhesive strength between the second fastener and thefirst fastener may be 9 N/cm or less. Adhesive strength between thesecond fastener and the first fastener is not particularly limited, butmay be preferably 0.5 N/cm or more, and more preferably 1 N/cm or more.In one or more embodiments of the present invention, adhesive strengthbetween the second fastener and the first fastener is measured as willbe described later.

In one or more embodiments of the present invention, wigs of variousdesigns can be produced using one wig kit as a result of separablyadhering the second fastener and the first fasteners to each other.

In one or more embodiments of the present invention, although notparticularly limited, from the viewpoint of enhancing fittability whenthe wig base cap is worn on a head, at least one of the first fastenersand the second fastener may preferably have elasticity, and morepreferably both the first fasteners and the second fastener may haveelasticity.

In one or more embodiments of the present invention, although notparticularly limited, the first fastener may preferably have a tapeshape. In one or more embodiments of the present invention, although notparticularly limited, the first fastener may have a thickness of 0.2 to0.6 mm, or have a thickness of 0.3 to 0.5 mm. In one or more embodimentsof the present invention, although not particularly limited, if the hairtress is fixed to the wig base cap as the hair member, the width of thefirst fastener is desirably larger than the width of the root portion ofthe hair tress, and the width of the first fastener may be 1.5 times ormore the width of the root portion of the hair tress, or be 2 times ormore the width of the root portion of the hair tress, for example.

In one or more embodiments of the present invention, although there isno particular limitation on the method for arranging the first fastenerson the wig base cap, from the viewpoint of workability, for example, itis desirable to arrange the first fasteners such that a length directionof the first fasteners extends in a lateral direction of the wig basecap (a circumferential direction of the head portion), and an intervalbetween positions at which adjacent first fasteners are arranged may bepreferably larger than the width of the first fastener. In one or moreembodiments of the present invention, although there is no particularlimitation on the method for fixing the first fasteners to the wig basecap, it is desirable to fix the first fasteners thereto such thatportions of first fasteners other than fixed portions move, for example.In one or more embodiments of the present invention, the first fastenersmay be sewn to the wig base cap, or the first fastener may be providedwith a crease and the first fasteners may be sewn to the wig base capalong the crease, for example. Also, in one or more embodiments of thepresent invention, although not particularly limited, a first fastenermay be fixed to the wig base cap using an adhesive such as a bond, or afirst fastener may be provided with a crease and fixed to the wig basecap along the crease using an adhesive such as a bond, for example. Fromthe viewpoint of increasing air permeability and comfort when the wigbase cap is worn and facilitating separation of a first fastener and asecond fastener, it may be preferable that only the crease portion ofthe first fastener be fixed to the wig base cap.

In one or more embodiments of the present invention, although notparticularly limited, the second fastener may preferably have a tapeshape. In one or more embodiments of the present invention, although notparticularly limited, the second fastener may have a thickness of 0.2 to0.6 mm, or have a thickness of 0.3 to 0.5 mm. In one or more embodimentsof the present invention, although not particularly limited, if the hairmember is a hair tress, the width of the second fastener is desirablylarger than the width of a root portion of the hair tress, and the widthof the second fastener may be 1.5 times or more the width of the rootportion of the hair tress, or be 2 times or more the width of the rootportion of the hair tress, for example. In one or more embodiments ofthe present invention, although not particularly limited, if the hairmember is a hairpiece, the width of the second fastener is desirablylarger than the width of a peripheral edge portion of the hairpiece, andthe width of the second fastener may be 1.5 times or more the width ofthe peripheral edge portion of the hairpiece, or be 2 times or more thewidth of the edge portion of the hairpiece, for example. Alternatively,in one or more embodiments of the present invention, although notparticularly limited, the second fastener may be provided to cover theentire base portion of the hairpiece.

In one or more embodiments of the present invention, it may bepreferable that an autohesion adhesive is disposed on one or bothsurfaces of a first fastener and one or both surfaces of a secondfastener. The second fastener and the first fastener can be separablyadhered to each other by using the autohesion adhesive. In one or moreembodiments of the present invention, an “autohesion adhesive” refers toan adhesive having properties such that adhesives of the same typeadhere to each other, and do not substantially adhere to anothersubstance. Because the autohesion adhesive is disposed on one or bothsurfaces of the first fastener and one or both surfaces of the secondfastener, the first fastener and the second fastener have adhesivenessonly to each other.

In one or more embodiments of the present invention, from the viewpointof enhancing fittability to the shape of a head, the autohesion adhesivemay preferably have flexibility after it has solidified. In one or moreembodiments of the present invention, although there is no particularlimitation on the autohesion adhesive, an adhesive compositioncontaining one or more adhesive components selected from the groupconsisting of natural rubber, natural rubber derivatives obtained bygrafting an unsaturated monomer onto natural rubber, and syntheticrubber can be used as the autohesion adhesive, for example, and from theviewpoint of good adhesion properties, it may be preferable to use anadhesive composition containing one or more adhesive components selectedfrom the group consisting of natural rubber and natural rubberderivatives obtained by grafting an unsaturated monomer onto naturalrubber. In one or more embodiments of the present invention, althoughthere is no particular limitation on an unsaturated monomer to begrafted onto natural rubber, examples thereof include methylmethacrylate, styrene, acrylonitrile, vinylidene chloride, maleicanhydride, acrylamide, vinylpyrrolidone, dimethylacrylamide, andglycidyl methacrylate. From the viewpoint of reliable progression of agrafting reaction, out of these compounds, methyl methacrylate, styrene,and acrylonitrile are normally used. Examples of synthetic rubberinclude acrylonitrile-isoprene copolymer rubber (NIR),acrylonitrile-butadiene copolymer rubber (NBR), styrene-butadienecopolymer rubber (SBR), butadiene rubber, and isoprene rubber. Naturalrubber and/or a natural rubber derivative may be used in combinationwith a synthetic rubber as adhesive components, and from the viewpointof increasing peel strength between the hair members and the wig basecap, when the total amount of natural rubber and/or a natural rubberderivative and synthetic rubber is 100 mass %, the content of thenatural rubber and/or the natural rubber derivative may be preferably 30mass % or more. The adhesive composition may include an additive agentsuch as an age resister as appropriate as long as the effects of thepresent invention are not inhibited. An antioxidant such as a hinderedphenol-based antioxidant can be used as the age resister, for example.Examples of the hindered phenol-based antioxidant include triethyleneglycol-bis[3-(3-t-butyl-5-methyl-4-hydroxyphenyl)propionate],pentaerythrityl-tetrakis[3-(3,5-di-t-butyl-4-hydroxyphenyl)propionate],octadecyl-3-(3,5-di-t-butyl-4-hydroxyphenyl)propionate,1,3,5-trimethyl-2,4,6-tris (3,5-di-t-butyl-4-hydroxybenzyl)benzene, and3,9-bis[2-{3-(3-t-butyl-4-hydroxy-5-methylphenyl)propionyloxy}-1,1-dimethylethyl]-2,4,8,10-tetraoxaspiro[5,5]undecane. In one or more embodiments of thepresent invention, although there is no particular limitation on theautohesion adhesive, a commercially available autohesion adhesive can beused. For example, latex-based adhesives in CORETEX (registeredtrademark) series that contain an adhesive component such as naturalrubber, natural rubber derivatives obtained by grafting methylmethacrylate onto natural rubber, synthetic rubber and so on and aremanufactured by MUSASHI CHEMICAL CORPORATION can be used. It may bepreferable that the autohesion adhesive is in a solidified state in thefirst fasteners and the second fastener.

In one or more embodiments of the present invention, although notparticularly limited, the first fasteners and the second fastener mayeach be constituted by a fastener base member in which the autohesionadhesive is disposed on one or both surfaces of an elastic fabric, ormay each be constituted by a fastener base member in which an elasticfabric is impregnated with the autohesion adhesive. In one or moreembodiments of the present invention, although not particularly limited,from the viewpoint of enhancing fittability when the wig base cap isworn on a head, the fastener base member may preferably have anelongation percentage of 130% or more, and more preferably have anelongation percentage of 150% or more in the length direction under aload of 14.7 N, the elongation percentage being measured according tothe JIS L 1096 constant-speed elongation method. In one or moreembodiments of the present invention, although not particularly limited,the first fasteners and the second fastener may each be constituted byan autohesion adhesive. There is no particular limitation on thematerial of the elastic fabric, and a fabric including polyurethanefibers, nylon fibers, or the like may be used, for example.

In one or more embodiments of the present invention, if the autohesionadhesive is a pressure sensitive adhesive that adheres to somethingunder pressure, the first fasteners and the second fastener can beeasily adhered separably to each other by bringing the first fastenersand the second fastener into contact with each other and then pressing acontact portion using a hand, for example. For example, if a pressuresensitive adhesive is used out of adhesive compositions including anadhesive component, such as natural rubber, natural rubber derivativesobtained by grafting an unsaturated monomer onto natural rubber, orsynthetic rubber, the first fasteners and the second fastener can beseparably adhered to each other by bringing the first fasteners and thesecond fastener into contact with each other and then pressing a contactportion using a hand.

In one or more embodiments of the present invention, although notparticularly limited, from the viewpoint of strongly fixing a hairmember to the wig base cap and facilitating a style change, for example,peel strength between the wig base cap and the hair member may bepreferably 20 to 50 N/cm, and more preferably 30 to 40 N/cm. In one ormore embodiments of the present invention, peel strength between the wigbase cap and the hair member is measured as will be described later.
